CAR-ROOF CONSTRUCTION.

Application filed September 15, 1911. Serial No. 649,433.

To all whom it may concern:

Be it known that we, WILLIAM S. BIBLE and JOSEPH A. COSTELLO, citizens of the United States of America, residing at Cleveland, in the county of Cuyahoga, State of Ohio, have invented certain new and useful improvements in Car-Roof Construction; and we .do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in car-roofs, and pertains more especially to an improved car-roof construction for a rail,

way box-car. K

One object of this invention is to dispense with a ridge-pole and purlins in building a roof of the character indicated and to obtain greater head-room in the car for which said roof is designed.

Another object is to produce a light roof which is simple and durable in construction;

Another object is to prevent blowing of snow, rain and cinders by the wind into the car between adjacent roofing-sheets of the car-roof.

With these objects in view, and to the end of attaining any other advantages hereinafter appearing, this invention consists in certain features of construction, and combinations and arrangement of parts, hereinafter'described, pointed out in the claims, and illustrated in the accompanying draw- 85 ings.

in the said drawings, Figure 1. is a top plan of a portion of a car-roof embodying our invention. Fig. 2 is a vertical section on line 2-2, Fig. 1, looking in the direction 4A3 indicated by the arrow. Fig. 3 is a central 'vertical section on line 3'3, Fig. 2, looking in the direction indicated by the arrow, and

"illustrates two adjacent carline and the metal roofing-sheet extending between said carlines. 1 Fig. 4 is a, vertical section on line 4-4, Fig. 3, looking in the direction indicated by the arrow. .Fig. 5. 'is a vertical section on line 5-5 Fig. 1, looking in the direction indicated by the arrow. Fig. 6 so is a vertical section online 6-6, Fig. 5, looking outwardly. Fig. 'i' is a vertical section on line 7+7,- Fig; 6', looking in the direction indicated by the arrow. -Figs. 3 to inclusive are drawn on the same as scale. but on a-larger scale than'Figs. 1 and,

as at a, (see Figs. 5, 6 and 7) to receive the 2, and portions are broken away in the drawings to reduce their size.

Referring to Figs. 1 and 2 of said drawlngs A and A indicate the two laterally spaced side plates of a car-roof. The side plates A are applied in any approved man'- ner and extend longitudinally of the roof. The side plates A and A are substantially horizontal and parallel, and each side plate has-its outer "side overlapped by car-siding C (see Figs. 2, 5, 6, and 7).

Metal carlines are arranged transversely and spaced longitudinally of the roof, and each carline preferably consists of a solid steel bar B which bridges the space between and is mounted on or supported from the side plates A at the top of the side plates. The said bar is preferably set into each side plate which is therefore recessed at its top,

bar. The said baris provided at its bottom with two flanges b which project laterally of the bar in opposite directions respectively and extend longitudinally of the bar, and said bar is therefore inverted-T-shaped 8G in cross-section. The said bar extends from the outer side of each side plate to the outer side of the other side plate and is provided at the outer side of each side plate with a downwardly projecting flange 10 which is shown abutting against the outer side of said side plate. The said bar slopes from the outer side of each side-plate upwardly toward a point centrally between the ends of the bar and is rigidly secured at its flanges 72 (see Figs. 2, 5, Gand 7) to the side plates by suitably applied bolts D, nuts (Z and washers 12.

The side plates A, the bars B and the spaces between said parts are covered by metal roofing which comprises metal roofingsheets E and metal caps G, and it will be observed that two suitably supported metal roofing-sheets E extend (see Figs. 3 and 6) from over oppositely projecting flanges b of each bar B laterally of the bar in opposite directions respectively and also extend longitudinally of the bar (see Figs. 1, 2, 4,5, and 7 and over' and beyond the outer'sides of the side plates, and each roof- 'ing-sheet E. extends from the outer side of each side plate A to the outer side of the other side plate and at the outer side of-each side plate (see Figs. 2, 5, 6 and 7) has a downwardly projecting end-portion c ar- 11o ranged at and overlapping the outer side of the car-siding C adjacent said side plate, and said roofing-sheet curves or slopes, as at 13, (see Figs. 3 and 6) upwardly over the adjacent flange b of the said bar to and is in contact with the adjacent side of the bar at a point above the said flange. Next to and in contact with the said side of the said bar the said roofing-sheet has an upwardly projecting side portion 1 1 which extends longitudinally of said bar and bridges the space between the side plates and terminates at a point below the top of said bar in a flange 15 which is arch-shaped in cross-section and projects laterally of the said side portion over and is spaced from the body of said roofing-sheet, which flange extends longitudinally of said side portion of-said roofingsheet and consequently longitudinally of the said bar. Each side portion 14 of each roofing-sheet E extends over each side plate A (see Figs. 5 and 7) and preferably to and beyond the outer side of said side plate.

By the construction illustrated and hereinbefore described it will be observed that each bar B forms a carline which is inverted- T-shaped in cross-section between the outer side of each side plate A and the outer side of the other side plate, that two roofing sheets are arranged at opposite sides respectively of the said bar and rest on the flanges of the bar, and that adjacent flanged side portions 14 of adjacent roofing-sheets E are oppositely arranged and contiguous to opposite sides respectively of the bar B snugly interposed between the said side portions of said roofing-sheets, and a cap G for said side portions of said roofing-sheets is provided, which cap extends 'from end to end of said side portions and over the top .of said bar and covers and extends longitudinally of the arch-shapedflanges 15 of said side portions of said roofing-sheets and'engages the outer sides of the outer portions of said flanges and holds said side portions of said roofingsheets in contact with said bar at a point above the flanges 'o the bar. Preferably said flanges 15 of said side portions of said roofing-sheets are resilient, andthe engaging cap presses somewhatagainst the outer sides of the outer portionsof said flanges, and the application of the-cap to said flanges places said flanges under tension. The said cap G is provided at the bottom'thereof and externally with two laterally and outwardly'pro jecting flanges 17 arranged at oppositesldes respectively and extending1 longitudinally of the cap and resting on t e bodies of the roofing-sheets E whose adjacent side portions 14 are covered by said cap, and the said cap extends from the outerside of each side plate A to the outer side of the other side plate and consequently from end to end of the adjacent carline and at the outer side of each side plate A (see Fig. 2) has an end masses portion 9 arranged at the outer side of the adjacent downwardly projecting end-portions e of said roofing-sheets and projecting downwardly below the adjacent downwardly projecting end flange ,10 of the said carline and attached 'to said'side plate A in any approved manner, as for instance, by suitably extends longitudinally of the said flanges and consequently longitudinally of the cap and extends over and across and longitudinally of the bar B interposed between said flanges, and it will be observed that each end portion g of said cap forms a downward extension, as at 23, of said passageway and that said extension'of said passageway conimunicates (see Figs. 5 and 7) with theexternal' atmosphere atthe lower extremity of said portion of said cap and consequently at the outer side of the adjacent car siding C. It will be observed therefore that said passageway 22-is in communication with the external atmosphere at the outer side of the car-siding overlapping the outer sides of the side plates; and thatv the space formed next below each arch-shaped flange 15 forms an air-conducting passageway which extends between the ends of and is in communication with the passageway 22 formed next over said flanges. Hence the aforesaid cap is adequately ventilatedinteriorly, but

obviously by the construction hereinbefore described-there is little liability of moisture and cinders obtaining ingress to the passageways or spaces formed along the flanges 15.

. By the constructlon hereinbefore described and illustrated in the accompanying drawings it will be observed that each barB projects upwardly above the adjacent flanges 15 and into the passageway 22.

formed next over the said flanges, but the cap covering the said flanges is high enough to have the said passageway extend over the top of the said bar. In other words, said cap has its top spaced'from the said flanges 15 and arranged over and spaced y from and extending across andlongitudi- .nally of the top of the adjacent bar Band forming an air-conducting passageway arranged, over and extending across and 1ong1- tu dinally of the top of the said bar and over and extending longitudinally of the said flanges. The upper portion of the said her,

the flanges15 adjacent said bar and the cap covering or extending over the top of the said bar and over and into engagement with the said flanges are therefore adequately ventilated and kept in a dry condition.

The cap G which covers adjacent side portions 14 of adjacent roofing-sheets E is large enough in dimensions vertically,- that is, extends far above the bar B which separates said portions of said roofingsheets,to accommodate the location within and centrally between the ends of the cap of a flanged plate H which is arranged next below and forms a seat for and braces or reinforces the top of the said cap centrally between the ends of the cap, which plate is provided with two depending flanges h arranged at opposite sides respectively of the upper portion of the said bar and riveted, as at 25, to the bar.

Mounted on each cap G centrally between the ends of the carline over which the said cap extends is the body or bottom member K of a saddle, and the top of said saddle consists of a horizontally arranged metal plate L mounted on the body or lower saddle-member K and forming a seat for three running-boards R which are arranged in the same plane horizontally and spaced transversely of the roof centrally between vthe side plates and extending longitudinally of the roof. The boards R are secured in place in any approved manner.. Preferably the topof each cap G centrally between its ends has a flat horizontally arranged portion 26 which rests on the plate H within said cap, and said plate is provided at its upper side and centrally with an upright stud 27 which extends vertically upwardly and loosely through said portion of the top of said cap and loosely through the members K and L of the saddle and above the plate or upper memberL of the saddle. A nut28 is screwed. onto the stud 27 at the upper side of the plate or upper saddle-member L and clamps the two members K and L of the saddle and the portion 26 of the top of the cap G to the plate or seat-forming member H. The body or bottom member K of said saddle is shown riveted, as at the cap.
